If only they hadn't criminalised abortion, and consistently cut funding to sex education and instead funded shit like "Crisis pregnancy centers".
Get your head out of your ass.
And before anyone even tries - I have no kids and want no kids, but to answer this bullshit with "don't have kids" is unhelpful at the very least, and actively licking boot at worst. These problems are not the fault of the people having kids.
Some people need sexual activity, and not all children are intended. Few of the children we have are actually adoptable, though there are safe surrender sites, and it would be interesting to see if they're being used more.
But sexual frustration figures largely in the motivation of the alt-right, also for rampage killers, spree killers, and Ted Kaczynski.
So sure, we can swear off sex, and some do. But it results in hundreds of thousands of War Boys eager to serve Immortan Joe and get witnessed all shiny and chrome into Valhalla.
There's also the problem of how the German Reich dealt with a population implosion. Himmler started his master-race program, arresting and detaining German women for a breeding program. It was highlighted recently in an article about the historical that inspired Margaret Atwood for the atrocities of Gilead in A Handmaid's Tale We're already seeing interest in rolling back women's rights and women's personhood here in the US.
Then you don't understand the complex reality in favor of a simplistic view. If that's what you need to do to cope in what is, granted, a terrifying reality, then you do you. But I cannot follow. Do what you will.
